SUNNYVALE — A Lodi man was arrested last week after authorities tied him to a pair of bank robberies in Sunnyvale and San Jose, according to the Sunnyvale Department of Public Safety.

Adam Kiedrowski, 28, was arrested Sept. 25 at a San Jose motel, the same day San Jose police released surveillance images of a man who robbed two U.S. bank branches. The robberies occurred Aug. 28 in San Jose and Sept. 5 in Sunnyvale.

In both cases, a man wearing a hooded sweatshirt and baseball cap walked up to a teller and demanded money while displaying a semiautomatic pistol in his waistband, then fled on foot with an undisclosed amount of cash.

Sunnyvale detectives pieced together physical evidence that led them to suspect Kiedrowski, and with the help of San Jose police they arrested him at the motel. He has been booked into County Jail on suspicion of armed robbery.
